Assistência TécnicaAs dicas apresentadas destinam-se a técnicos de eletrónica, a tentativa de reparação ou assistência sem ter conhecimentos de eletricidade e eletrónica, podem provocar danos mais graves aos equipamentos e, devido a tensões muito elevadas em alguns circuitos, graves danos fisicos que podem constituir um risco em determinadas reparações.

Não arrisque reparar equipamentos com tensões elevadas se não tiver conhecimentos técnicos para o fazer em segurança.
